I received a call from this number, they claimed to be a law firm. When I picked up they immediately said "This is not a telemarketing call, we are a law firm" The message was pre-recorded. They said they needed to speak with what sounded like a jumble of first names "Charles Alexander David" or something to that effect. The recording prompted me to call the number 1-866-535-0621 and quote a reference number. I did not call the number. Call seemed suspicious.
Yeah, I've started getting their calls too. (2 yesterday, 3 today on my cell) Sometimes it's automated and sometimes it's a live person. They are Deanne Natale Law Offices. From what I've "Googled" they are shysters, and break a lot of laws and rules. They take advantage of the fact that the average person doesn't know all the detailed laws or what their rights are. Pay nothing to them - don't even talk to them or return their calls. They appear to be calling on a debt I've never heard of before (Wells Fargo???? WTF?) But I think they are really just a collection agency with someone who has some kind of title, calling someone who has no debt whatsoever. If you do have an old debt (or recent) contact your creditor and find out if they know anything about these shysters. Chances are they don't.
The phone number they give you to call back is different from the above number, but can be looked it up on this site for a lot more info. (866-577-5823 & 888-653-1524)
